Sc5511A_Open_Device; Sc5511A_Closedevice - SIGNALCORE SC5511A Operating & Programming Manual

Function: sc5511a_close_device
Definition: int sc5511a_close_device
Input: sc5511a_device_handle_t
Description: sc5511a_close_device closes the device associated with the device handle and turns off
the "active" LED on the front panel if it is successful.
Example: Code to exercise the functions that open and close the PXIe device:
#include
// Declaring
#define
sc5511a_device_handle_t *dev_handle;
int num_of_devices;
char
int status;
device_list = (char**)malloc(sizeof(char*)*MAXDEVICES);
serial numbers to search
for (i=0;i<MAXDEVICES; i++)
SCI SN has 8 char
num_of_devices = sc5511a_search_devices(device_list);
SCI for device type

}
printf("\n There are %d SignalCore %s USB devices found. \n
num_of_devices, SCI_PRODUCT_NAME);
device_list[i]);
//** sc5511a_OpenDevice, open device 0
dev_handle = sc5511a_open_device(device_list[0]);
// Free memory
//
// Do something with the device
// Close the device
status = sc5511a_close_device(dev_handle);
